This air-to-air photograph shows a Boeing B-17 Flying Fortress in flight, its ball turret, tail gun position, and tall vertical fin clearly visible in profile. The simplified star-only national insignia, without the red bar surround added in mid-1943, dates the image to the early years of American involvement in World War II, when the B-17 was becoming the backbone of the Eighth Air Force's daylight bombing campaign over Europe.
